UEFN and Matchmaking Errors

We are aware that some creators are unable to start a session in UEFN. Creators may also be receiving cooking errors when trying to push changes to UEFN islands, and players trying to join UEFN islands may receive matchmaking errors. We are looking into these issues and will provide an update when we have more information or a fix.
